Answer:
96-8k = 3k+63
96 - 11k = 63
(you get -11 by bringing the +3k to the other side which changes the sign to -3k ; -8k-3k = 11k)
-11k = 63 - 96
-11k = -33
k = -33/-11
k= 3

Solve write the differences 505-167=
Answer:
338 is the difference
Step-by-step explanation:
505-167=338
The difference between 505 and 167 is calculated using standard subtraction techniques, including borrowing, to arrive at a final answer of 338.
Explanation:To solve the subtraction problem 505 - 167, we can use the standard algorithm for subtraction:
Start by writing the numbers vertically with the larger number on top:505- 167Subtract the rightmost digits: 5 - 7. Since 5 is less than 7, we need to borrow from the tens place.After borrowing, we have 15 - 7, which equals 8.Now, move on to the tens place. Remember, we borrowed 1 from here, so it's 0 now, not 1. 0 - 6 can't be done, so we borrow again from the hundreds place. It's now 10 - 6, which equals 4.Finally, in the hundreds place, we have 4 (since we borrowed 1) minus 1, which equals 3.Write down the results to get the final answer: 338.The difference between 505 and 167 is 338.
Convert `[-3,oo)` to inequality notation use the variable x.
Answer:
x≥-3
Step-by-step explanation:
the bracket means the the number is inclusive, so the answer would be
x≥-3
Final answer:
To convert the interval [-3,∞) to inequality notation, we would write x ≥ -3, indicating that x includes -3 and extends to positive infinity without an upper bound.
Explanation:
To convert the interval notation [-3,∞) to inequality notation using the variable x, we consider the meaning of the interval. The square bracket [ indicates that the number -3 is included in the interval, which corresponds to x ≥ -3. The infinity symbol (∞) suggests that there is no upper bound to the values of x, hence the interval does not include any particular largest number, which is why the parenthesis ) is used rather than a square bracket. Therefore, the equivalent inequality notation for the interval [-3,∞) is x ≥ -3.

Step-by-step explanation:
See the attached figure to represent the question
let the number of packages of Italian style = x
let the number of packages of French style = y
let the number of packages of Oriental style = z
Italian style ⇒ 0.4 kg of zucchini, 0.3 kg of broccoli, and 0.3 kg of carrots.
French style ⇒ 0.5 kg of broccoli and 0.5 kg of carrots.
Oriental style ⇒ 0.2 kg of zucchini, 0.3 kg of broccoli, and 0.5 kg of carrots.
The amount of zucchini ⇒ 17,800 = 0.4x + 0 * y + 0.2z
The amount of broccoli ⇒ 28,300 = 0.3x + 0.5y + 0.3z
The amount of carrots ⇒ 38,900 = 0.3x + 0.5y + 0.5z
Solving the 3 equations together to find x , y and z
Using the calculator:
x = 18,000 ⇒ Italian style packages
y = 14,000 ⇒ French style packages
z = 53,000 ⇒ Oriental style packages

Plz answer number 3!
If two or more points have the same domain or x value, then it is not a function because points cannot have identical x values, only y values.
With this in mind, C is not a function because there are two 4s in the domain.
So looking at this our answer would be C because when you are trying to find if it is not a function you have to look for repeated X values or domains if there I s a problem with a repeated X value that would not be a function but if the Y values were to repeated that doesn’t really matter so yeah. Hopefully this helps!

Answer:
The midpoint of points [tex](-2,-2)\ and\ (4,6)[/tex] is [tex](1,2)[/tex].
Step-by-step explanation:
Given points are [tex](-2,-2)\ and\ (4,6)[/tex]. We need to find the midpoint of the line segment.
The formula of finding midpoints between the point [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is
[tex](\frac{x_1+x_2}{2}),(\frac{y_1+y_2}{2})\ Equation(1)[/tex]
W have points [tex](x_1,y_1)=(-2,-2)[/tex]. And [tex](x_2,y_2)=(4,6)[/tex]
Let us plug the value in Equation (1)
[tex](\frac{-2+4}{2} ),(\frac{-2+6}{2})[/tex]
[tex](\frac{2}{2}),(\frac{4}{2})\\ \\(1,2)[/tex]
So, the midpoint of points [tex](-2,-2)\ and\ (4,6)[/tex] is [tex](1,2)[/tex].
Tricia completed the square of the quadratic function f(x) = x² + 14x + 2 and determined the coordinates of the minimum value are (-7, - 47). Which equation must be Tricia's result?
f(x = (x +7)² + 47
f(x) = (x + 7)² - 47
f(x) = (x - 7)² + 47
f(x) = (x - 7)² - 47
Answer:
The co-ordinates which give the minimum value for the quadratic function are (-7, -47)
Step-by-step explanation:
i) the quadratic function f(x) = [tex]x^{2}[/tex] + 14x + 2
= [tex]x^{2}[/tex] + 14x + 49 - 49 + 2
= [tex](x + 7)^{2}[/tex] - 49 + 2
= [tex](x+7)^{2}[/tex] - 47
ii) The minimum value of the result of the quadratic equation in i) will be achieved when [tex](x + 7)^{2}[/tex] is zero as any square value is always positive and thus the minimum value of a square is always zero.
iii) [tex](x + 7)^{2}[/tex] is zero when x = -7 and when x = -7 then y = f(x) = -47
iv) The co-ordinates which give the minimum value for the quadratic function are (-7, -47)
Consider g(x) = −x^2 + 12x − 32 Part A: Write g(x) in vertex form, identify the vertex, and determine the x-intercepts.
Answer:
(x - 6)² = - (y - 4)
The vertex of the parabola will be (6,4).
The x-intercepts are at (8,0) and (4,0).
Step-by-step explanation:
Given the equation of parabola is g(x) = y = - x² + 12x - 32 .......... (1)
Now, converting the equation to vertex form.
Here, y = - x² + 12x - 32
⇒ y = - (x² - 12x + 36) + 4
⇒ y - 4 = - (x - 6)²
⇒ (x - 6)² = - (y - 4) ........... (2) (Answer)
Now, the vertex of the parabola will be (6,4) and it opens down. (Answer)
Let the x-intercept of the parabola is at (h,0).
Hence, from equation (2) we get,
(h - 6)² = - (0 - 4) = 4
⇒ h - 6 = ± 2
⇒ h = 8 or h = 4
Therefore, the x-intercepts are at (8,0) and (4,0). (Answer)

Emma has n containers. She will put
cup of berries into each container.
Which expression represents the total amount of berries, in cups, that Emma will put into the containers?
The total amount of berries, in cups, that will be in Emma's containers is represented by the expression n in mathematics , due to the multiplication principle of counting.
Explanation:The subject of this question is mathematics, specifically, arithmetic and algebra. Emma has n containers and plans to put one cup of berries into each container. To find the total amount of berries, in cups, that Emma will put into the containers, you multiply the number of containers by the number of cups per container. Since Emma is putting 1 cup of berries in each container, the expression that represents the total amount of berries Emma will put into the containers is simply n.
This is due to the Multiplication Principle of Counting, which states that if one event can occur in m ways and a second can occur independently of the first in n ways, then the two events can occur in m x n ways. Here, the two events are 'number of containers' and 'cups of berries per container', with the 'number of containers' being variable, represented as n and the 'cups of berries per container' being a constant '1'.

Find 66 2/3 precent of 87. Find 1 precent of 3,620
62 1/2 precent of x is 5 what is x. 300 precent of k is 42 what is k
Final answer:
To find percentages of numbers, convert the percent to a decimal and then multiply. To find the unknown quantity in an equation involving percentages, divide the given number by the percent expressed as a decimal.
Explanation:
To find 66 2/3 percent of 87, first convert the percent to a decimal by dividing it by 100: 66 2/3 ÷ 100 = 0.6667. Then multiply the decimal by 87: 0.6667 x 87 = 58.33. So, 66 2/3 percent of 87 is approximately 58.33.
To find 1 percent of 3,620, divide 3,620 by 100: 3,620 ÷ 100 = 36.2. So, 1 percent of 3,620 is 36.2.
To find x in the equation 62 1/2 percent of x is 5, first convert the percent to a decimal: 62 1/2 ÷ 100 = 0.625. Then divide 5 by the decimal: 5 ÷ 0.625 = 8. So, x is 8.
To find k in the equation 300 percent of k is 42, first divide 42 by 300: 42 ÷ 300 = 0.14. So, k is 0.14.

What are the missing measures in the diagram
Answer:
J=67
T=67
G=180-67-67
St=5
HJ=3.7
Step-by-step explanation:
The two triangles are equal.
Since the triangle at isosceles, two sides/angles are equal.
The measure of the angles and the sides are:
m∠J = 67
m∠T = 67
m∠G =46
ST = 5 cm
HJ = 3.7 cm
We have,
ΔGHJ ≡ Δ STU
This means,
The corresponding sides and angles are the same.
Now,
GH = ST = GJ = SU = 5cm
And,
HJ = TU = 3.7 cm
Now,
The sum of the angles in the triangle = 180
In GHJ,
m∠J = 67
This is because angles opposite to the equal sides are the same.
Now,
∠G + ∠H + ∠J = 180
∠G + 67 + 67 = 180
∠G = 180 - 134
m∠G = 46
And,
m∠T = 67
Since ΔGHJ ≡ Δ STU.
Thus,
The measure of the angles and the sides are:
m∠J = 67
m∠T = 67
m∠G =46
ST = 5 cm
HJ = 3.7 cm
